摘要

The contour hedgerow was considered as an effective alternative measure of stone dike in the utilization and management of slope land. However, there are still some doubts in the applications. Based on the results of experimental plots and field trial in the Three Gorges Area, the objective of this study was to discuss the structure and function of contour hedgerow-intercropping system in order to offer some practice references for applying it. The system was consisted of two main parts, the hedge and intercrops. After contour hedgerows implemented three years, the available soil depth rang from 50 to 60cm that is much deeper than slope land, while slope become gentler. With the result that the soil water capacity was extended and that soil fertility was promoted. The hedgerows may also produce many kinds of agricultural products, such as medicinal plants materials, forage for cattle, forage for silkworm, tea and other food when you selected suitable species. The contour hedgerow-intercropping system can spread in the region where is difficult to construct stonewall terrace. It is a suitable way to reform and use slope land, control slope soil erosion, and ensure agriculture sustainable development in mountainous and hilly area.
